A planet in Federation space, near the Romulan border. Galorndon Core is barely inhabitable - electromagnetic storms frequently rage across the surface, and prolonged exposure to these is dangerous to Humans and Romulans. In 2366 the Enterprise investigated a crashed spacecraft on the planet and found it to be a Romulan vessel.9 The Enterprise-D again visited the planet in 2368 whilst investigating a Romulan plot to attack Vulcan.10

Fourth planet of the Gamma Tauri system. The Ferengi stole a T-9 energy converter from Gamma Tauri IV in 2364.17

The planet was colonised in 2363. In 2366, the USS Lovell spent an extended period on colony support at the planet. During the same year Jeanne Vinueza took over as the Colony Leader on the planet. One of her first actions was to reject protectorate status from the Federation, claiming independence for the colony. In foregoing Starfleet protection she hoped that the planet would not attract the attentions of the Klingons in the increasing climate of hostility with the Federation.18

Gamma Tauri IV was an agricultural colony. It lacked any deposits of dilithium. The planet had a single landmass, an irregular crescent shape that stretched almost two-thirds of the planet's circumference, covering latitudes from the subarctic to subantarctic. It totalled more than a third of the entire planet's surface area.18

In 2266 the Shedai launched a massive attack on the Federation colony on Gamma Tauri IV, killing thirteen thousand people. In response Commodore Reyes ordered the Starship Endeavour to enact Starfleet General Order 24. The ship bombarded the surface, exterminating every living thing, blasting away its atmosphere, cooking its oceans, and leaving it as nothing but a red-hot ball of glass.18

A Federation planet in the Taurus Reach. In 265 the USS Bombay was scheduled to pick up a team of dilithium prospectors who had been stranded on Getheon when their warp drive failed. The Bombay was unable to complete the mission as she was destroyed in orbit of Ravanar IV by a Tholian fleet.31

This world is the home planet of the Ghorusdan species. When the Federation made first contact with the planet 47 members of the USS Adelphi's crew were killed, at least in some part as a result of Tam Elbrun's actions.32

Planet in the Klovari system. A population of mermaids live on this world. In 2377 Q's son Q stole the Delta Flyer and took it to the Klovari system with Icheb, suggesting that they could swim with the mermaids.35
